Abstract
An apertured, compression-resistant web is disclosed, the web comprising a first surface having a plurality of microapertures forming volcano-shaped surface aberrations, a second surface generally parallel to and spaced apart from the first surface. A plurality of fluid passageways extend between the first surface and the second surface to place the first surface and the second surface in fluid communication with one another. The web is formed of a multilayer polymeric film comprising at least one rigid layer and at least one substantially less rigid layer joined to the rigid layer. In a preferred embodiment, a rigid layer has an elastic modulus of at least 120 kpsi, a substantially less rigid layer has an elastic modulus of not greater than 75 kpsi. The multilayer film is preferably formed by coextruding a rigid layer comprising a blend of polystyrene and polypropylene, and a substantially less rigid layer comprising a blend of LDPE and LLDPE.
